What is the value of x so that the mean is 5. 7, x, 5, 3, 2
Answer:
8
Step-by-step explanation:
The 'mean' is the same as the 'average'
( 7 + x + 5 + 3 + 2) / 5 = 5
7+x+5+3+2 = 25
x = 8

John has a bag of different colored marbles. He has 6 red marbles, 3 blue marbles, 7 yellow marbles, and 5 green marbles. If John reaches into the bag and randomly pulls out a marble, what is the probability that the marble will be blue? (If necessary, round to the nearest tenth.) (as a percent please!!)
Answer:
P(blue) ≈ 14.3%
Step-by-step explanation:
probability P is calculated as
P = ( favourable outcome ) ÷ ( total number of possible outcomes )
here favourable outcome is blue of which there are 3
number of possible outcomes is the total = 6 + 3 + 7 + 5 = 21
P(blue) = [tex]\frac{3}{21}[/tex] = [tex]\frac{1}{7}[/tex]
to convert to a percentage multiply the fraction by 100%
P (blue) = [tex]\frac{1}{7}[/tex] × 100% = 100% ÷ 7 ≈ 14.3% ( to the nearest tenth )
Answer:
14.3%

Find the zeros of the function p(x) = -9x^2 + 1
Step-by-step explanation:
zeroes = x intercept.
to find the x intercept we let y or in this case p(x) = 0
Hence,
-9x^2 + 1 = 0
-9x^2 = -1
x^2 = 1/9
x = 1/3

Describe the change in the graph of the parabola f(x) when it transforms into g(x) = two thirdsf(x).
The parabola g(x) will open in the opposite direction of f(x), and the parabola will be narrower than f(x).
The parabola g(x) will open in the same direction of f(x), and the parabola will be narrower than f(x).
The parabola g(x) will open in the opposite direction of f(x), and the parabola will be wider than f(x).
The parabola g(x) will open in the same direction of f(x), and the parabola will be wider than f(x).
Answer:
(d) opens the same; wider
Step-by-step explanation:
Multiplying a function by a constant has the effect of vertically scaling the graph of the function by a factor equal to that constant.
__
Here, you're multiplying by 2/3, so each y-value is 2/3 of its previous distance from the x-axis. The effect on the graph of a parabola is to make it "flatter", hence wider in appearance. This does not change the direction in which it opens.
The attachment shows an example.

Answer:
y = (1/4)x + 20
Step-by-step explanation:
The general equation of a line is
y = mx+ b , where m is the slope of the line and b is the y-intercept of the line ( where the line intersects the vertical y-axis)
From the graph we can see that the line intersects the y-axis at 20, so our y- intercept is b = 20
Now will find the slope of the line, and for that we need any two points from the line.
For example let's pick points ( x1= 0, y1 = 20) and ( x2 = 4, y2 = 21)
the slope m = (y2-y1)/(x2-x1) = (21-20)/ (4-0) = 1/4
slope of the line is m = 1/4
The equation of the graph shown in the graph is
y = (1/4)x + 20

The equation is 6(2x-1), where X is more than 0. When a shipping company charges $6 to ship a package that weighs up to 1 pound.
What is the equation?
In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
A shipping company charges $6 to ship a package that weighs up to 1 pound and $2 for each additional pound or portion of a pound.
lets make an assumption that the total weight of the shipment is x pound and cost for shipping is y.
the shipping company charges $6 for the first pound.
Up to now, the charge is y=6
After 1 pound, i.e for the remaining (x-1) pounds, they charge $2 per pound.
So, the total charge will be, y=6+2(x-1)
weight is always starting from zero as there is no negative weight.so X>0
so the equation is 6(2x-1), where X is more than 0

Work out the probability that this marble will be a green marble.
Using it's concept, it is found that there is a 0.7818 = 78.18% probability that this marble will be a green marble.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
There are two ways to end up with a green marble selected.
Green in bag A(6/10 probability) and in bag B(9/11 probability).Red in bag A(4/10 probability) and green in bag B(8/11 probability).Hence, the probability that this marble will be a green marble is given by:
